why programs that do the exact same thing use different amount of resources?

yeah... why? I am running windows 7 pro x64 bits, with a i5 and 4GB ram. I am always trying to find low resource usage programs because, for some reason, I suffer from high Ram usage sometimes. so, I tested foxit PDF reader and Sumatra PDF reader. so, Foxit has way more features, but both use 50-60MB of RAM. why does that happens? is it not supposed that sumatra, since has less features and less options, should use less RAM than foxit?
this is a general question, I used Sumatra and foxit as examples only. this question is for all the programs.
 
Solution
Depends on how the program is written, some may have far less features but are coded poorly and leave snippets of code out their using resources when not doing anything.
